2015 Cadillac ATS Coupe favors cleanliness over radical lines

Though you might not know it from looking at vehicles like the XTS and Escalade, if you take a broader look at history, you'll see that Cadillac models have gotten a lot smaller from the tail-finned highway cruisers of old. At least when it comes to coupes, anyway. The Eldorado, in particular, kept getting smaller until it disappeared, its place taken in recent years by decidedly more compact XLR, CTS Coupe and ELR hybrid. What you see here, however, is Cadillac's smallest coupe yet.
Revealed today at the Detroit Auto Show is the new 2015 Cadillac ATS Coupe, the brand's first compact two-door coupe, and the first production car to wear the brand's all-new crest. It shares the same platform and wheelbase as the existing ATS sedan, but packs a wider track and unique bodywork that's decidedly more conservative and less unique in its angular styling than the CTS Coupe that it's likely to ultimately displace in the Cadillac lineup. Styling aside, the all-American luxury marque has engineered the ATS Coupe with a focus on reducing weight to the benefit of both performance and fuel economy, giving it near 50/50 weight balance front to rear with underbody aerodynamic elements helping it cheat the wind.
Buyers will be able to choose between two engines: a 2.0-liter turbo four and a 3.6-liter V6.

Weekly Recap: 2016 CTS-V gives Cadillac new momentum for the new year

It's been a rough year for Cadillac. The historic luxury carmaker been in the news for all of the wrong reasons: Declining sales, ditching its advertising agency and the relocation of its headquarters from Detroit to New York. But in late December, Cadillac reminded everyone what it does best: Build some of the rawest and most compelling luxury sedans in the world, as evidenced by the 2016 CTS-V. This monster churns out 640 horsepower from a supercharged 6.2-liter V8. Sound familiar? That's the Corvette Z06 engine, and it makes this CTS the most powerful production Cadillac ever. It also puts the sporting divisions of the Germans on notice. The new CTS-V easily overpowers the Mercedes-Benz E63 AMG S 4Matic and its 5.5-liter biturbo V8 rated at 577 hp, and the BMW M5 (with the competition pack) and its 4.4-liter twin-turbo V8 that pushes out 575 hp. The rear-wheel drive Cadillac can sprint to 60 miles per hour in 3.7 seconds, which is close to the 3.5-second time turned in by the 4Matic-driven E63 S, and a bit quicker than the 4.1 seconds posted by the M5. With Magnetic Ride Control, General Motors' stout eight-speed automatic transmission (also used in the Corvette), Brembo brakes and a carbon-fiber option package that pretty much builds your car out of carbon fiber – it's clear this Cadillac means business. Truth be told, we expected this CTS-V to deliver. It's been a serious sports sedan for a decade, and the recent generation and its 556-hp arrogance have been particularly memorable. But notice what we're doing here? We're talking about product. Not who makes Cadillac's ads, or if the brand's headquarters has a mailing address in NYC. Like the 2016 ATS-V that's due in the spring, the debut of the 2016 CTS-V (on sale in late summer) is a shot in the arm for Cadillac, and its arrival comes during time of transition. The brand is trying to reinvent itself as a modern luxury maker. It wants new customers, a different image and obviously more sales. Those things are going to take time, but with a 640-hp sledgehammer of a sports sedan on tap for next year, Cadillac can still maintain some of its swagger through all of the change.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
